Specification of Letters Patent.

'10 ltlll whom it Ill/my concern.-

Be it known that 1, Jones OTTo OBER- MAIER, a subject of the King of Bavaria, r'esidingin the town of Lambreeht, in the Rhenish Palatinate, German Empire, have invented a certain new and useful Im rovement in Apparatus for Treating Textile Fibers with Liquids and Gases, of which the following is a specification.

This invention relates to an apparatus for treating textile fibers and fabrics with liquids and gases for dyeing urposes. By means of this apparatus all t 1e operations necessary are carried out in quick, safe, and )erfect manner, while the pressure under which the work is performed may be readily controlled.

The accompanying drawing represents a vertical longitudinal section of my improved apparatus.

An outer receptacle a is provided with a tightly-fitting cover I) and incloses two bearings c. inner perforated receptacle (1, adapted to receive the material to be treated; Receptacle d is mounted on a horizontal hollow perforated shaft e, supported by bearin s 0. By arranging shaft 6 of receptacle (1 in a IOIiZOIltal position numerous practical advantages result over a vertically-placed shaft, when receptacle (1 operates as a centrifugal. Shaft e is connected at one end to a umpf by tube g, while its other end is coup ed to a powershafth, carrying pulley 11. Receptacle a is connected with an air-chamber k or the airpump 1 and with the dye-reservoir m by means of the tube n. When the materialreceptacle (1 is therefore properly fitted in the receptacle a, the pumpfis set in motion and drives the prepared iquid from receptacle m by means of the tube e through the material. The liquid then arrives in the receptaele a and flows from here directly through the tube n to the dye-reservoir'm, whence it again be ins its circulationthat is to say, it is suckef up by the pump by means of tube 0.

If the dyeing operation is completed, vessel (1 is rotated by shaft 72, to throw the liquid re.-

Within receptacle a is contained an maining in said vessel "out by centrifugal ac' tion. This liquid will enter vessel a and flow from said vessel through pipe a back into reservoir m. By simultaneously operating the air-pump Z all the above-described operations may be performed either in vacuum or under an excess ofpressure.

With my invention it is possible to get along with a small but concentrated tity of dyeing liquid, because the materlal to be dyed is not surrounded wholly by the li uid, but lies free. The liquid is always 00 lected in a dye-reservoir which is placed lower than the material-receptacle and may driven uniformly through the material-receptacle. It is evident that this material-receptacle may be taken off or uncoupled in a very simple manner, while the amount of the driving power necessary is much less than with upright eentrifugals. Further, it is possible to carry out the various steps in any desired succession or to repeat them any desired number of times.

ters Patent of the United States, is

A dyeing-machine consisting of a material, receptacle d mounted on a hollow horizontal shaft and made as a centrifuge situated in a vessel a and connected with a pump f g,

voir m situated lower than the vessel, as also with a vacuum apparatus 1: by the insertion of connections between the latter, for the purpose of .ell'ecting all of the usual operations "during the dyeing process with the least possible consumption of liquid in any order of succession and'repetition, under pressure as well as under vacuum, without changing the position of the material.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
